Just a side note, we stayed at the Borgata last year, I signed up for their rewards card. Didn't gamble much at all. Came home and went online and "registered" my account, making it an online thing. Logged into that a couple weeks ago, saw the word "COMP", clicked on it, got 2 free nights. Signed up for the 2 free nights, then looked at it yesterday and I've got 2 more free nights.
So it pays to register and stay up with that stuff. 2 free nights at the Borgata isn't too shabby. It's a beautiful place. If you wanted more than 2 nights, the rates were seriously reduced.
